Didn't see anywhere else but Mugen posted some new pictures, which I think might actually answer the mystery bumper people assumed was for the 2019-2020 around the nurburgring.

The cars are pretty outrageous looking but remember the full Mugen DC2R was pretty extreme too. (but the intake, twin loop, suspension and other parts were great) Looks like some cooling changes as well as perhaps some performance options, hopefully more info will be published after the coming Japanese Auto Shows.

Some info from from Autoblog:

Mugen calls it the RC20GT, and it's based off the current Type R.

Out back, the tri-tipped, trick exhaust is replaced by one rather restrained pipe — that pipe happens to lead back to a full titanium exhaust. That bumper is made of carbon fiber, with the side skirts and new wing following suit. We do like the new 20-inch forged wheels. A "pro-spec" adjustable suspension is added, along with better brakes and bucket seats sporting harnesses. Though one drive of the Type R will have you wondering how Mugen managed to make a better braking system than Honda in that car.

Power remains the same, but 306 horsepower and 295 pound-feet of torque is plenty for the front wheels to handle. Do keep in mind this is a concept design, so as of now, you won't be seeing any Civics trawling around the streets with this ... face. To see this Mugen you'll have to go to the Tokyo Auto Salon, where Mugen has a few other custom cars like a Mugen Insight and CR-V on the stand.

MUGEN CIVIC TYPE R Prototype

Really don't like the wheels.. but otherwise, hopefully its functional.
